Calculate the LCM of 780,266,989,675

Given numbers are 780,266,989,675

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 780,266,989,675 is 4616948700.

Find LCM of 780,266,989,675 with Prime Factorization


2 780, 266, 989, 675
3 390, 133, 989, 675
5 130, 133, 989, 225
26, 133, 989, 45

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 5 x 26 x 133 x 989 x 45 = 4616948700

Therefore, the lowest common multiple of 780,266,989,675 is 4616948700.

LCM Formula to Find Lowest Common Multiple of 780,266,989,675

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

780 x 266 x 989 x 675 = 138508461000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

266 : 1, 2, 7, 14, 19, 38, 133, 266

989 : 1, 23, 43, 989

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,266,989,675, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

266:2x 7x 19

989:23x 43

675:3x 3x 3x 5x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 5 = 30

Therefore, the value for common factors is 30.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 138508461000/(1x30)

LCM = 138508461000/30

LCM = 4616948700

Thus, we can understand that the LCM of 780,266,989,675 is 4616948700.
